Thanks filip kenens, could you post Google Play link for "disk speed test" you mean? I suppose for PC you mean Parkdale: http://www.the-sz.com/products/parkdale/ Good. Is the developer of anothe program I use (Seaside) Sorry, I seems too meticolous, but to have coherent results we need to be precise P.S. there is also an Android version of Parkdale. I'll test it when I'll have some time to.
Is it so difficult to post the Play Store link? Is it this one? https://play.google.com/store/apps/details?id=us.hipxel.performance.disk.speed.test Doing a search for "disk speed test" in Google Play Store doesn't return any app named exactly "disk speed test", the closest is the one above. Else, is not available in my country.
Sorry for no answer from me. I did some speed tests both on PC and X9S, but with doubt results. I'll try to do some more, when coherent I'll post here. Hope some others will do the same and report here.
